Don't assume that because it's a compiler it's necessarily faster. There are
other factors with a much bigger impact on performance than the final code
generation. It depends on your actual workload: if it's dominated by
sorting, for example, then compiling isn't going to help. Don't make a
decision based on performance until you have made measurements that are
model your workload.

Not at that level, no!
